Vehicle lighting system based on infrared light sources and vehicles comprising a matrix lamp controller

Abstract

The invention relates to a vehicle lighting system based on infrared light sources, the vehicle lighting system comprising: an infrared matrix lamp, which comprises a plurality of infrared light sources arranged in a matrix and which is configured to be mounted on a vehicle to provide an illumination range with respect to the vehicle, wherein each of the plurality of infrared light sources corresponds to an illumination region in the illumination range; and a matrix lamp controller configured to turn on, when a target region needs to be illuminated, an infrared light source in the infrared matrix lamp corresponding to the target region on the basis of relative position information between the target region and the vehicle, wherein the relative position information comprises an angular position of the target region relative to a vehicle reference. The invention further relates to a vehicle comprising the vehicle lighting system.

The invention claimed is: 
     
       1. A vehicle lighting system based on infrared light sources, the vehicle lighting system comprising:
 an infrared matrix lamp, which comprises a plurality of infrared light sources arranged in a matrix and which is configured to be mounted on a vehicle to provide an illumination range with respect to the vehicle, wherein each of the plurality of infrared light sources corresponds to an illumination region in the illumination range; and 
 a matrix lamp controller configured to turn on, when a target region needs to be illuminated, an infrared light source in the infrared matrix lamp corresponding to the target region on the basis of relative position information between the target region and the vehicle, wherein the relative position information comprises an angular position of the target region relative to a vehicle reference. 
 
     
     
       2. The vehicle lighting system according to  claim 1 , wherein the infrared matrix lamp further comprises a mounting plate for mounting the plurality of infrared light sources, a convex lens provided in front of the plurality of infrared light sources, and a front cover provided in front of the convex lens, such that infrared light emitted from the infrared light sources is transmittable through the convex lens and the front cover to illuminate the target region. 
     
     
       3. The vehicle lighting system according to  claim 2 , wherein the infrared light source is an infrared light-emitting diode, and the mounting plate is a printed circuit board. 
     
     
       4. The vehicle lighting system according to  claim 2 , wherein the infrared matrix lamp further comprises a base and a housing; the mounting plate, the convex lens and the housing are mounted to the base such that the mounting plate and the infrared light source thereon are located in an inner cavity of the housing; and the front cover is mounted at a front end of the housing. 
     
     
       5. The vehicle lighting system according to  claim 1 , wherein the relative position information further comprises distance information of the target region relative to the vehicle, wherein the matrix lamp controller is further configured to adjust the brightness of the turned-on infrared light source on the basis of the distance information. 
     
     
       6. The vehicle lighting system according to  claim 1 , wherein in the matrix lamp controller, there is a mapping between the relative position information and an infrared light source range in the infrared matrix lamp corresponding to the relative position information, and the matrix lamp controller turns on the infrared light source corresponding to the target region on the basis of the mapping. 
     
     
       7. A vehicle, comprising a low beam system, a high beam system, a radar apparatus for sensing relative position information between the target region and the vehicle, and the vehicle lighting system according to  claim 1 . 
     
     
       8. The vehicle according to  claim 7 , further comprising a vehicle-mounted camera for recognizing an object within the target region when the infrared matrix lamp illuminates the target region. 
     
     
       9. The vehicle according to  claim 8 , wherein the infrared matrix lamp is integrated in the low beam system or the high beam system of the vehicle.
